응급 폐동맥 색전 제거술로 진단 및 치유된 폐동맥내 융모막 암종
Choriocarcinoma in the Pulmonary Artery Diagnosed and Treated by Emergency Pulmonary Embolectomy
A 43-year-old woman who had had an invasive mole 5 years previously required emergent pulmonary embolectomy under cardiopulmonary bypass. Curative resection was impossible because the tumor invaded the right main pul- monary artery and left lower pulmonary artery. The pathologic diagnosis made by the tumor emboli specimens was choriocarcinoma. The patient received post-operative chemotherapy over a 6-month period and had complete remis- sion. Although rare, choriocarcinoma should be considered in the differential diagnosis of fertile women presented with pulmonary embolism.
